网上下载的VCSA6.5，由于里面密码过期，所以安装是肯定会出问题的，具体解决办法如下：
1 密码重置失败password reset failed
是因为下载的非官方的包密码过期了，如果是Windows引导安装：
安装完虚拟机的时候就马上执行下面步骤，修改密码有效期即可。
重启vcsa，在引导界面（photon的图形界面）里按e编辑启动项
在consoleblank=0 后面添加rw init=/bin/bash，F10启动
进入命令行后，执行passwd -x 700 root，将密码有效期延长(chage -l root可查看到期时间，可把700写出2000等更长）
执行passwd修改root密码！最好修改成和你安装页面填写的密码一致
运行umount / 和reboot -f
2 IP配置失败
指定的ip配置不成功，可能会变成dhcp，只需要手工进去改了就行了
3 域名解析失败
So I got a response from vmware tech support on this, and the only thing that worked for me was this: Pause the install process right before phase 2. Open a console to the appliance, enable SSH On the appliance, echo "::1 localhost.localdom localhost" >> /etc/hosts Continue the installer and magically it works. This shouldn‘t really matter, but it does, so I figured I‘d let people see if it fixed their issues. Their first recommendation was basically most people‘s problem: forward and reverse DNS should work before you install. But if your DNS is happy and the appliance still hates life, it appears to also care about v6 lookups.

如果出现主机识别不了internal error等错误，是DNS没有配置的问题：
可以在第一步配置ip时设为dhcp先。
